Improved YOLOv8n Algorithm for Contact Network Insulator Detection

中文摘要英文摘要

针对高速铁路接触网绝缘子检测易受气候环境因素干扰,且存在精度与效率欠佳的问题,文章提出一种改进算法AB-FP-YOLOv8.该方法首先构建C2f-AFE模块,旨在强化全局上下文特征提取能力,抑制复杂背景干扰;继而将颈部网络替换为BC-Neck结构,以提升目标细节捕捉能力;进一步采用Powerful-IoU损失函数优化定位性能,降低误检率;同时增设160×160分辨率的小目标检测头,增强对小尺寸绝缘子的识别能力.实验结果显示,相较于原YOLOv8n模型,ABFP-YOLOv8模型在参数量减少的情况下,mAP@50和mAP@50-95,以及推理速度均有所提升.该算法适用于移动检测端部署以及检测环境复杂多变的场景.

In view of the susceptibility of high-speed railway insulator detection to climatic and environmental factors,as well as the deficiencies in accuracy and efficiency,this study proposes an improved algorithm ABFP-YOLOv8.This method first constructs a C2f-AFE module to strengthen the extraction ability of global contextu-al features and suppress complex background interference.Subsequently,the neck network is replaced with a BC-Neck structure to enhance the ability to capture target details.Furthermore,the Powerful-IoU loss function is em-ployed to optimize the localization performance and reduce the false detection rate.Additionally,a 160×160 small target detection head is added to enhance the recognition ability of small-sized insulators.Experimental re-sults indicate that,compared with the original YOLOv8n model,the ABFP-YOLOv8 model achieves improve-ment in mAP@50 and mAP@50-95,increase in inference speed,despite reduction in the number of parameters.This suggests that the algorithm is highly suitable for deployment in mobile detection terminals and scenarios with complex and variable detection environments.
